This creates an optical virtual private network for each client signal. ITU-T defines an optical transport network as a set of optical network elements (ONE) connected by optical fiber links, able to provide functionality of transport, multiplexing, switching, management, supervision and survivability of optical channels carrying client signals ...
Automatically Switched Optical Network (ASON) is a concept for the evolution of transport networks which allows for dynamic policy-driven control of an optical or SDH network based on signaling between a user and components of the network. [1]
Optical networking is a means of communication that uses signals encoded in light to transmit information in various types of telecommunications networks.These include limited range local-area networks (LAN) or wide area networks (WANs), which cross metropolitan and regional areas as well as long-distance national, international and transoceanic networks.
Software running on a network management system terminal, e.g. workstation, dumb terminal or laptop housed in an exchange/central office. Transport of network management data between the network management system terminal and the SONET/SDH equipment, e.g. using TL1/Q3 protocols.
An optical mesh network is a type of optical telecommunications network employing wired fiber-optic communication or wireless free-space optical communication in a mesh network architecture. Most optical mesh networks use fiber-optic communication and are operated by internet service providers in metropolitan and regional but also national and ...
Rouskas' research on network design and optimization has specifically concentrated on solving a variety of optical design problems. He developed a novel ILP (integer linear program) formulation for network optimization, improving scalability and achieving optimal solutions for large-scale SONET ring instances. [ 28 ]

Automatic Switched Transport Network (ASTN) allows traffic paths to be set up through a switched network automatically. The term ASTN replaces the term ASON (Automatically Switched Optical Network) and is often used interchangeably with GMPLS (Generalized MPLS). This is not completely correct as GMPLS is a family of protocols, but ASON/ASTN is ...
